PRESERVING. AND FREIGHT CAR.

SPECIFICATION forming part of Letters Patent No. 236,789, dated January 18, 1881.

Application filed March 3,1880. (ModeL) To all whom it may concern:

Be itknown thatI, ORsEMUs G. DAVIS, of the city of Ludington, in the county of Mason and State of Michigan, have invented certain new and useful Improvements in Preserving-Oars and Freight-Oars; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a side elevation of my car, partly broken away to show my improvements. Fig. 2 is a view of the stove and pipe, and Fig. 3 is a transverse sectional view of the car;

The nature of my invention relates to a carbody for preserving articles during transportation; and my improvement relates, essentially, to means for maintaining the air within the preserving-room of the car at a required temperature, as set forth in the following description, and pointed out in the claim.

In the drawings, Adesignates the car-body, and B its roof, which is provided with the usual center strip, 0, and side guards, D. Upon the platform are arranged the ordinary guards E and any suitable or well-known braking devices.

The car-body is divided into two compartments, one of which, G, is used as the stoveroom, and the remaining compartment, H, as the preserving-room. The walls of the preserving-room are disposed as' follows, so as to constitute a series of walls with spaces between them, to wit: A wall, I, is constructed Within the car-body so as to leewe a space, I, between the said wall I and the wall I of the car-body. The opposing faces of the walls I 1 are lined with zinc and the space between them filled with charcoal. The wall I is lined inside with heavy stiff paper, and an air-space, K, left between this wall and the next inner wall, L, which is also lined inside with like paper. An air-space, M, is also left between the wall L and the last inner wall, N, which last-named wall is lined with zinc upon its inner face. At the lower corners of the preserving-compartment are gutters or water-ways P, to collect any water therein, and this may be carried by short pipes into the stove-room. The spaces between the aforesaid walls have ribbing R, and apertures R are made through the paper and paper-lined walls, so that the spaces between them will communicate. At the corners of said walls are angle-straps, which strengthen the structure.

It may here be observed that no bolts pass entirely through the walls, since the metal thereof would communicate cold to the preserving-chamber.

The doors S, which open into the preserving-chamber, are formed with spaces similar to the above-described walls, and are formed with beveled edges adapted to fit closely into the sills.

T designates the stove-pipe, from which a heating-pipe, U, extends into the preservingroom, and thence back again to the stove-pipe. In the two branches of the pipe U, between the stove-pipe and the partition V, are valves V, both valves being controlled by a single stem, V In the stove-pipe, between the arms of the pipe, is arranged a valve, U, the method of heating the preserving-room being as follows:

The valve U being closed and the valves V opened, heat will pass into the pipe U, and thence back into the stove-pipe and up through the flue, which extends up through the roof. When the valves V are closed, however, and the valve in the stove-pipe opened, heat will be shut off from the pipe which leads into the preserving-room, and the heat will then pass directly along the stove-pipe and up through the flue.

To determine the temperature of the preserving-room I provide a thermometer, W, at one end of the said room, which is visible through an opening, W, having glass windows.

In summer ice may be used in the stoveroom in lieu of a stove, and any suitable means employed for conducting the cold air into the preserving-room. Suitable means will in such case also be provided for collecting such drippings as may occur in the stove-room. The

car-top will be provided with suitable pipes, preserving-room and. returning therefrom to W, for purposes of ventilation. the pipe T, substantially as and for the pur- What I claim isposes set forth.
